DRAWING-BOARD.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Application led July 10, 1917. Serial No. 179,625.

u citizen of the Dominion of New Zealand,

and residing at The Iindsor, Khyber Pass Road, Auckland, in the Provincial District of Auckland, in the Dominion of New Zealand, have invented certain new and useful Improvements in Drawing-Boards, of which the following is a specification.

This invention relates to boards used in oiiices, schools and elsewhere for retaining a sheet of paper while a drawing is made thereon, and provides a simple and effective means for securing the paper without the use of drawing pins.

The invention consists in providing at the top and bottom of the board a paper fastener or grip, which does not exceed the thickness of the drawing board, and consequently does not impede the free use of a T square, set square or other instrument.

The fastener or grip comprises battens or strips attached to the top and bottom of the board by means of screws passing freely through slots near the ends of the battens. The heads of the screws lie in sloping or curved recesses, so that the batten or strip is forced against the edge of the board when the said batten or strip is moved in either direction. The length of the batten or strip approximates to the length of the board, and its inner face is rounded to admit the edge of asheet of paper freely between the board and the batten or strip.

The drawing herewith illustrates the invention and will now be referred to for the purposes of a detailed description Figure l, is an elevation,

Fig. 2, a plan, and

Fig. 3, an end elevation partly in section of the board.

The board l is made in any ordinary manner, and is provided with battens or strips 2 and 3 extending approximately to the full length of the board. The thickness of each batten does not exceed or is somewhat less than the thickness of the board, so that there v `is no projection above the surface of the board to impede free use of drawing instruments.

The batten 2 is attached to the top edge of the board by screws 4 passing through slots 5 near the ends of the batten, and the other batten 3 is attached to the bottom edge of the board by screws 6 passing through 'slots 7 near the ends of the said batten.

The heads of the screws ll and 6 Alie in curved or sloping recesses 8, so that whichever wayr the batten is moved longitudinally the curved or sloping faces of the recesses pass beneath the heads of the screws and force the batten against the edge of the board.

The inner edges 9 of the battens are rounded to admit the edges of the sheet of paper 10.

The sheet of paper is usually cut to a size slightly greater than the width of the board and its upper edge is inserted between the edge of the board and the batt-en 2, which is moved longitudinally to grip the paper. The lower edge of the paper is then inserted between the lower edge of the board and the hatten 3 and gripped thereby.

If the size of the sheet of paper is less than the size of the board its upper edge is gripped by the batten 2 only.

What I do claim and desire to secure by Letters Patent of the United States is l. The combination with a drawing board,

lof strips at the upper and lower edges of rounded for the purpose specified.

In testimony whereof I have signed my name to thls speclication in the presence of two witnesses.

E. HINTON.
